Title: Divided flywheel
Inventor: JACKEL JOHANN
IPC: F16D13/00
Filed: 1991-05-30
Granted: 1995-02-22
Abstract: Apparatus for transmitting torque from the engine to the variable-speed transmission of a motor vehicle has a primary flywheel which is connectable to the crankshaft of an engine, a secondary flywheel which is coaxial with and is rotatable relative to the primary flywheel against the opposition of one or more dampers and is connectable to the input shaft of a transmission by the clutch plate of a friction clutch having a cover which is permanently separably affixed to the secondary flywheel. An antifriction bearing between the two flywheels is located at least in part radially inwardly of fasteners which extend through holes in the first flywheel to separably connect the first flywheel to the crankshaft. At least one race of the at least one bearing is or can be integral with one of the flywheels.

Title: Silicon-on-insulator capacitive surface micromachined absolute pressure sensor
Inventor: MASTRANGELO CARLOS HORACIO
IPC: G01L1/14
Filed: 1994-03-21
Granted: 1997-01-22
Abstract: A method and structure for forming a capacitive transducer having a deformable single crystal diaphragm. A first well region is formed within a semiconductor substrate in an SOI wafer having a sacrificial layer of known thickness and a top single-crystal silicon layer thereon. Next, a silicon epitaxial layer is deposited on the top silicon layer for forming a flexible single crystal membrane. The epitaxial layer and the sacrificial layer are masked and etched to define the flexible diaphragm. An electrical insulating conformal support layer is deposited on the substrate and attached to the diaphragm so as to seal the sacrificial layer therebetween. An access opening is etched through the diaphragm, and then a wet etchant is inserted through the access opening for removing the sacrificial layer, thereby defining a diaphragm cavity between the remaining epitaxial layer and the substrate. The thickness of the diaphragm cavity is substantially equal to the thickness of the sacrificial layer removed from the SOI wafer. Conductive ions are diffused into facing sections of the diaphragm and the first well of the substrate so as to define fixed and deformable electrodes of the sensing capacitor. Next, a plug is selectively deposited within and for sealing the access opening without substantially reducing the volume of the diaphragm cavity. In this manner, a deflection of the flexible diaphragm in response to variations between the ambient pressure and the pressure sealed within the diaphragm cavity causes a o corresponding change in the capacitance between the first well region and the conductive region in the diaphragm. A reference capacitive sensor of similar construction is also provided for ratiometric pressure measurements. A pressure transducer manufactured in accordance with this process is also described.

Title: Image enhancement method and circuit using quantized mean-matching histogram equalization
Inventor: KIM YEONG-TAEG
IPC: H04N19/136
Filed: 1997-08-14
Granted: 1998-12-09
Abstract: An image enhancement circuit and a method therefor including the steps of quantizing the level of an input image signal, obtaining a cumulative density function on the basis of a gray level distribution of a screen unit with respect to the quantized image signal, outputting a cumulative density function value interpolated on the basis of the quantized cumulative density function value, calculating the mean level of the input image signal in a screen unit, and controlling a transform function to map the input image signal to a gray level and map the mean level to itself, by using the interpolated cumulative density function as the transform function. In addition, the image enhancement method includes the steps of outputting a compensated mean level by adding a corrected value depending on a predetermined correction function to the mean level, and controlling the interpolated cumulative density function as a transform function to map an input image signal to a new gray level on the basis of the interpolated cumulative density function value and to map the mean level to the compensated mean level. Thus, contrast is enhanced, and the mean brightness of a given image is continuously maintained.

Title: Pressure impulse series production system - connects servo-motor alternately to hydraulic pressure and return pipes
IPC: F15B/
Filed: 1975-04-17
Granted: 1979-11-10
Abstract: Linear or rotary vibrations are produced by hydraulic forces in servo-motors, by feeding to the hydraulic servo-motors a series of hydraulic pressure in pulses. This is done by connecting rapidly and alternately a pipe leading to the servo-motor to the hydraulic pressure and return pipes. Where th servo-motor is double-acting, the pressure impulses can be applied to the opposite sides of the motor in antiphase. At each changeover, a quantity of oil under pressure can be fed to the servo-motor slightly large than that discharged to the return pipe. The actual pressure can be varied during an impulse, so that the amplitude of the vibrations can be controlled.

Abstract: The present invention concerns a method to prepare tubular shells made of copper or copper alloys in continuous steel casting system. The first phase is aimed at obtaining an oblique support through cool plastic deformation, said element being set on one end of a semi-processed, tubular element. During the second phase said semi-processed element is given a curved form, while during the third phase a mandrel is set inside said element, the external dimensions of said mandrel being equal to those of the shell to be obtained. During the fourth phase said element passes through a mould, the dimensions of which are such that said element is deformed to make the internal side of said element adhere with the external surface of said mandrel. During the fifth phase at the end of the processing line, an axial force operates on the mandrel, said force being opposite to the force exercised in the previous phase, while a final edge of said element is set on contrasting sectors under the processing line.
